The Focusing Optics X-ray Solar Imager (FOXSI) is a sounding rocket experiment designed to demonstrate focusing imaging and spectroscopy of the solar hard X-ray emission, in order to study the fundamental processes of energy release in the solar corona. Previous solar-dedicated hard X-ray instruments have used indirect, Fourier-based imaging techniques with limited dynamic range and sensitivity. Due to recent technological advances, focusing optics for hard X-rays are now available and have been optimized and demonstrated for solar observations with the FOXSI sounding rocket experiment. This has made it possible to observe faint coronal sources of hard X-ray emission near sources of energy release. The FOXSI rocket flew three times in 2012, 2014 and 2018. During the last two flights, observations have been coordinated with the Interface Region Imaging Spectrograph (IRIS). In this presentation, we will give an overview of the FOXSI experiment and the various observations obtained during the flight, with a particular focus on the coordinated observations with IRIS and the science enabled by the combination of sensitive HXR imaging spectroscopy and UV high resolution spectroscopy and imaging. |
